Make a 3D object into 2D slices

I'm thinking of an app that would take a 3D object and convert it into interlocking 2D slices (like SketchChair, but for all kinds of objects--I'm thinking specifically of those cardboard deer heads you can get from Urban Outfitters and other places). It would take a lot of the guesswork out of making complex forms!
